S?ECIFICATION 101 Application filed April t, lFMi.

f0 all whom, it nuty concern.-

Be it known that I, Sinner. G. Mcllin- LAND, ofthe city and State of New York, have invented an Improvement in Sewer-Connections for \Vater-(Jlosets, ofwhich the following is a specification.

In the best quality of plumbing it is usual to employ eastiron pipe in sections, set together with ealked lead joints, for the sewerpipes. These are fon'nd to be the most durable and the least liable to injury by concussion, by the shrink age of wood-work and other forces that are liable toinjure lead pipe or the wiped joints of the same; but it has hereto fore been diflicult to make a perfect joint at the surface of the floor between the upper end ofthe iron sewer-pipe and the porcelain end of the discharge-pipe in water-closets.

My improvement relates to the joint at the upper end of the iron pipe, whereby the connection can be made at the surface of the floor between the porcelain flange of the watereloset basin and the cast-iron pipe without risk of breaking the flange in making the connection, and without any difficulty being ex perienced in placing the closet in the correct position independently of the direction in which the sewer-pipe may pass away.

In the drawings, Figure 1 is a vertical tion of the upper end of the sewer-pipe lower end of the closet basin or trap, Fig. 2 is a plan below the line a;

The upper end of the sewer-pipe A terminates as a horizontal metallic flange, 13, at or near the level of the floor. Preferably such flange is countersunk into the wood, so as to be level. The lower end, (1, of the escapepipe of the water-closet or of the trap, intervening between the water-closet and the soilpipe, enters into the pipe A, and is provided wit-h a flange, D. This pipe 0 and flange D will usually be of porcelain where my im provemcnt is made use of; but I do not limit myself in this particular.

When the water-closet is set in place, it frequently happens that the bolt-holes through the flange D do not correspond to the holes in the flange B; hence other holes have to be bored in order that the watereloset basin may stand correctly in its relation to the front secand and FOR \NATER=CLOSETS.

, of the scat. To obviate this difficulty I make the openings for the bolts 0 in the flange D in the form ofseginental slots, as seen in Fig. 2, and I tap into the flange B female screws for the reception of the ends of the screws 6, and I apply washers 2 between the heads of the screwbolts and the flange D. By this construction I am able to dispense with the separate nuts heretofore used, and to insert the bolts down from above, and to screw theflange D upon a packing ofindia-rnbberatl, to make a tight joint without the risk of breaking the flange, and to place the closet in its correct position t3 the seat. If bolts with separate nuts are made use of, the bolt is liable to revolve when the nut is being tnrncd,and a nut cannot be introduced to advantage below the flange 13. It isprefcrable to makethese bolts of brass, so that they may not become rusted into the metal flange, and hence can be easily removed for repairs. In almost all instances the vertical sewer-pipe is at some distance from the center of the closet or trap, so as to hence it is usually necessary to introduce a branch pipe from the main vertical pipe to the closet. \Vhen lead is used for this branch pipe, the same is liable to injury from the shrinkage of timbers and the settling of the building, and it is often punctured by articles falling or being thrown into the water-closet, and the joint cannot be calked, andisliablc to become loose and allow gas to escape.

In order to introduce a branch pipe from the main vertical sewer-pipe to the closctin as small aspace as possible, I cause the pipe A to pass off at an inclination below the flange 13, so as to reach the hub Q upon the vertical pipe It as directly as possible. This pipe A is to be of iron, and united to the hub Q in the most firm and reliable manner by a tightlycalked lead joint. This pipe A can be placedin any desired direction beneath the floor, so as to pass to the said hub Q, as shown; but in so doing the holes in the flange B might stand in the wrong position for the screws 0 when the water closet is correctly placed. To avoid this difficulty I make the upper end of the pipe A as a short vertical cylinder, with a screw-thread around the outside of the same, and the flange be fastened into a corner or against a wall;

B is annular,with a screw-thread in the interior to screw upon the exterior of this end of the pipe A; hence this flange B can be partially revolved horizontally, even after the serewse are in place, so as to bring the front of the water-closet square with the seat-frame. \Vhen the screws 0 are tightened up, the packingZ is pressed upon the upper end of the pipe A, and the parts are rendered rigid and gas-tight, and the friction of the packing prevents the flange B revolving upon the end of the pipe A. The flange B is preferably made of brass, so that the screw-threads will not rust. It may be unscrewed from the pipe A While the latter is being calked into its hub and passed up to its place. The screw-flange can be screwed down upon the pipe until it takes a proper bearing upon the floor.

I claim as my inventionl. The combination, with the metal sewer pipe A and flange B, of the delivery-pipe C of the closet or trap, having the flange D around it, with segmental slots in the same, andthebolts 0, passing through such slotsinto screw-threaded holes in the flange B, substantially as set forth.

2. The cast-iron sewer-pipe, in combination with a horizontal flange screwed upon the upper end, and having screw-holes in such flange, a dischargepipe from a closet or trap passing into the upper end of such sewerpipe,and having a flange and bolts to connect the flanges together, substantially as set forth.

3. In combination with the cast-iron sewerpipe R and the branch hub Q upon the same, the inclined cast iron pipe A, passing into such hub Q, and calked, and the separate flange B, secured upon the upper end of the pipe A, occupying a horizontal position at or set forth.
